Check Digit Verification of cas no
The CAS Registry Mumber 823-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 823-72:
(5*8)+(4*2)+(3*3)+(2*7)+(1*2)=73
73 % 10 = 3
So 823-72-3 is a valid CAS Registry Number.

1-AZABICYCLIC COMPOUNDS. 24. SELECTIVITY OF POSITION OF NITRATION OF 1,2-DIHYDROPYRROLIZINE, 5,6,7,8-TETRAHYDROPYRROCOLINE AND PYRROLE HOMOLOGS

The selectivity of the position of nitration of 1-methylpyrrole, 1,2-dimethylpyrrole, 1,2-dihydropyrrolizine, and 5,6,7,8-tetrahydropyrrocoline was found.In contrast to the selectivity of substitution during nitration of their carbocyclic analogs, o-xylene, indane, and tetraline, the fraction of the α-nitro-isomer in the nitration products of 1,2-dimethylpyrrole is smaller than the fraction of α-nitro derivatives of 1,2-dihydropyrrolizine and 5,6,7,8-tetrahydropyrrocoline, and in the latter cases the isomers are almost equally distributed.During nitration of the above bicyclic pyrroles, the Mills-Nixon effect does not appreciably influence the selectivity of the position of the reaction.
